Solve the following linear inequations in R


Answer :

Given




2(5 – 2x) < x – 30


10 – 4x < x – 30


10 – 4x – 10 < x – 30 – 10


–4x < x – 40


x – 40 > –4x


x – 40 + 40 > –4x + 40


x > –4x + 40


x + 4x > –4x + 40 + 4x


5x > 40



x > 8


Thus, the solution of the given inequation is (8, ∞).
